Title: Vehicle-mounted ultrasonic detector
Inventor: SASAKI HAJIME
IPC: G01S15/93
Filed: 1992-12-22
Abstract: PURPOSE:To improve system reliability by stopping the operation of a detector and alarming that the detector is at halt by detecting the whizzing sound which is generated by driving of a vehicle mounting the detector after the power of the detector is turned on. CONSTITUTION:A wave-transmission signal from an operation control part 3 is output to air from a microphone part 9 through a reverberation absorption part 8. If there is an object, it reflects the signal and converts the signal to an electrical signal by the microphone part 9 again. The signal is transmitted to a waveform-shaping part 6 through reception wave signal amplification parts 10 and 5 and enters the control part 3. When the signal from the waveform-shaping part 6 is input within a constant amount of time from the output of the wave-transmission signal, a display signal is output to a display part 7 and alerts a user as an obstacle. After the power is turned on, the presence or absence of whizzing sound is checked during the system check of a detector 1. Then, if there is the whizzing sound, an alarm is sent out and the system operation is stopped, thus preventing erroneous operations.
